Items are getting inserted and displaying as buttons as expected, but the buttons and menu itself is not picking up the styles correctly. If I do:

<ribbon:Menu>

<ribbon:Button Label="Item #1" />

</ribbon:Menu>

Then the styles are correct. By incorrect styles, I mean, there is no light gray bar on the left of the menu, it is not sized properly (much smaller when databound), etc. Do I need to do anything else to pick up the correct styles? As a reminder, this is 2011.1 build :).
